Implementation of lean six sigma in public road transportation

Abstract

This paper presents the defect identification, defect reduction and continuous improvement in public road transportation by using lean six sigma methodologies. Lean methodologies will reduce the waste i.e. unnecessary efforts or tasks. The main aim of lean is to improve productivity i.e. to increase profit to the organization. The six sigma methodologies are centered towards the elimination of variations i.e. reduction of defects. The main objective of six sigma is 3.4 defects per million opportunities, whichlead to fulfilling the customer requirements. The six sigma tools arearithmeticaland statistical based. The lean mainly focused on the flow and the six sigma mainly focused on the problem. By combining, these two methodologies and implementing in public road transportation will leads to increase the profit of the organization and customer satisfaction. The results achieved by using DMAIC methodology and lean tools.
